If file /u01/app/oracle/oradata/orcl/ex1.dbf was unintentionally renamed or moved, restore it 2. If you have an export of tablespace EX1, then drop and re-create the tablespace and import the data. 3. Contact Oracle Support Services if the preceding recommendations cannot be used, or if they do not fix the failures selected for repair Optional Manual Actions ======================= 1. Shut down, mount the database and try flush redo using ALTER SYSTEM FLUSH REDO TO 'standby name' command. Then perform a Data Guard role change (failover). Available standbys: orcl1by.
